Specification of Letters Patent.

Patented Feb. 4, 1919.

Application filed May 25, 1918. Serial No. 236,448.

To all whom it may concern:

Be it known that I, HENRY B. HURNI, a citizen of the United States,residing at Waterbury, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in Watches; andI do hereby declare the following, when taken in connection with theaccompanying drawings and the characters of reference marked thereon, tobe a full, clear, and exact description of the same, and which saiddrawings constitute part of this application, and represent, in

Figure l a view in central transverse section of a watch constructed inaccordance with my invention.

Fig. 2 a broken detached sectional view on an enlarged scale showing oneedge of the center-band of the watch-case.

Fig. 3 a broken edge view on the same scale showing the watch-movement.

Fig. & a broken view of the back of the watch with the back-cap removed.

Fig. 5 a broken sectional view showing one of the screws employed forsecuring the movement in the case.

My invention relates to an improvement in watches, the object being toreduce the cost of their construction by reducing the thickness of thestock used in the production of the center-band, and to improve thecharacter of the seating of the watch-movement therein.

With these ends in View, my invention consists in a watch characterized[by having the front edge of its center-band formed with a seating-beveland by having its front movement-plate formed with a correspondingbevel.

11 carrying out my invention, as herein shown, I form a seating-bevel 2in the front edge of the center-band 3 which in other respects may be ofany approved construction, the said bevel 2 being of greater width thanthe thickness of the stock used in the production of the center-band. Ialso form the outer edge of the front movement-plate with acorresponding bevel 5 which seats upon the bevel 2 as clearly shown inFig. 1. The bevel 5 is seated upon the bevel 2 by means of such screwsas are ordinarily employed in securing watch -movements in watch-cases.One of these screws 6 is shown in Fig. 4:, this screw being mounted inthe movement in position to engage with the rear edge 7 of thecenterband. These fastening screws, wherever located, will operate todraw the movement from front to rear so as to seat the bevel 5 upon thebevel 2 not only firmly, but in such a manner as to compensate for anyvariations in the construction of the case and front movementplate. Byemploying the construction described, I am enabled to use much thinnerstock in the production of the center-band 3 than it is possible to usein watches as ordinarily constructed, in which the front movement-plateis formed with an overhanging edge or flange fitting intoa square rabbet1n the edge of the center-band, which construction does not providecompensation for inequalities. In my construction the front and rearedges of the center-band 3 are formed with shoulders 8 and 9 upon whichthe bezel l0 and back-cap 11 of the case are snapped in the.usualmanner. It will be observed that the shoulder8 is arelatively deepshoulder, and is located in the horizontal plane of the seating-bevel 2,the said bevel and shoulder forming the opposite faces of theflange-like front edge of the center-band, whereby the thickness of thewatch is reduced.

I claim In a watch, the combination with a sheetmetal center-band havinga flange-like front edge the inner face of which forms a beveled seat ofgreater width than the thiclmess of the stock from which the band isformed; of a front movement-plate having its front edge formed with abevel, a back movementplate, and a screw passing through the backmovement-plate into the front movementplate and having its headoverlying the inner edge of the center-band for seating the bevel of thefront movement-plate upon the said beveled seat of the band.

In testimony whereof, I have signed this specification in the presenceof two subscribmg witnesses.
